Abstract: An integral revolution clutch is provided wherein a motor rotates a drive pulley which continuously drives an idler pulley through a belt. A drive shaft is provided with a segment of a circle thereon connectable to the idler pulley by means of the belt. A spring means urges the segment into contact with the belt and a stop means normally prevents contact. When the stop means is deactivated, the segment is drawn between the belt and the pulley, causing the shaft on which the segment is located to make an integral number of revolutions until the stop means is restored. In a similar manner, power can be taken directly from the drive pulley.
